This semi-structured interview format offers a time-efficient method for gathering and recording information and scoring the PCL-R and PCL:SV. Similar to semi-structured interview schedules used by clinicians--facilitates a rapid accumulation of data. Scoring is complete by the end of the interview. Directly links data to individual items, allowing forensic experts to defend their scoring. Uses a format that is familiar to clinicians. Items are scored consecutively, and arranged in an order that allows rapid scoring (related items grouped). Appropriate for clinical, forensic, and research settings. Allows for an easy check of inter-rater reliability of each protocol. Tailored to an individual evaluation. Eliminates the need to purchase multiple forms (use for both PCL-R & PCL:SV). Reduces administration time by a third to a half. Developed through use in over 400 PCL-R and PCL:SV evaluations in a major forensic psychiatric hospital, and initially published in Gacono (Ed. ), A Clinical and Forensic Interview Schedule for the Hare Psychopathology Checklist (Lawrence Erlbaum Associates, 2000), the CFIS has been utilized in over a dozen clinical and forensic settings, with good inter-rater agreement and sound validity.
